Universal base structure for power distribution device building of transformer substation

Abstract

The invention discloses a universal base structure for a power distribution device building of a transformer substation. The universal base structure comprises a plurality of first steel bars, a raftpoured from concrete, and a column pier arranged on the raft, wherein the column pier comprises a #-shaped steel frame, a support column and a column leg reinforcing pier; the #-shaped steel frame isflatly laid and embedded into the raft, and welded and fixed to the adjacent first steel bar in the raft; the support column is vertically connected into the central area of the #-shaped steel frame in an insertion manner, a receiving groove used for receiving a part of the support column is arranged in the central area of the #-shaped steel frame, the support column is welded and fixed to the groove wall of the receiving groove, and a plurality of studs are welded to the outer circumferential surface of the support column; and the column leg reinforcing pier is poured from a plurality of second steel bars and concrete, and wrapped at the bottom of the support column, and the second steel bars comprise a plurality of longitudinal bars which are arranged at the periphery of the support column and a plurality of stirrups connected with the plurality of longitudinal bars.

Description

technical field [0001] The invention relates to the construction field, in particular to a general-purpose basic structure for a power distribution device building of a substation. Background technique [0002] In recent years, with the rapid development of my country's economy and society, the power system construction has been greatly developed, among which the construction of substations is a key node in the construction of power systems, and the state stipulates that the site selection of substations should "conform to the relevant national land use Policies, try to make use of the original wasteland, sloping land, and bad land.” Due to poor geological conditions, this puts forward higher requirements for the basic structure of the substation. [0003] In the prior art, the substation power distribution device building generally adopts a frame structure, and the foundations of the 220kV and 110kV power distribution device buildings are different, which lacks flexibility, ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the substation power distribution device building generally adopts a frame structure, and the foundations of the 220kV and 110kV power distribution device buildings are different, which lacks flexibility, and due to the installation of equipment, the load at the foot of some columns is relatively large. Large, requiring higher capacity column footings and foundation structures
